Linux搭建nexus私服

左手的ㄟ右手 2021-06-10 20:38 435阅读 0赞

### 1、linux安装maven ###

先解压maven的压缩包apache-maven-3.6.1-bin.tar.gz   命令: tar -zavf apache-maven-3.6.1-bin.tar.gz

然后编辑linux的环境变量属性:vim etc/profile

在末尾添加如下代码

export MAVEN_HOME=/root/home/websoft/maven/apache-maven-3.6.1
    export PATH=$MAVEN_HOME/bin

### 2、配置中央仓库的镜像:(因为国内访问阿里的网站快一些,换成了阿里的) ###

vim  /root/home/websoft/maven/apache-maven-3.6.1/conf/setting.xml

在<mirrors>标签下加入仓库配置的信息

<mirror>  
　　<id>alimaven</id>  
　　<name>aliyun maven</name>  
　　<url>http://maven.aliyun.com/nexus/content/groups/public/</url>  
　　<mirrorOf>central</mirrorOf>  
</mirror>

### 3、下载nexus并启动 ###

官网：[https://www.sonatype.com/download-oss-sonatype][https_www.sonatype.com_download-oss-sonatype]

提供一个分享链接：https://pan.baidu.com/s/1WWDOHN3Q3nX4\_9\_cIefLPg 提取码: 8k29

下载好是一个zip文件nexus-2.12.0-01-bundle.zip，通过ftp上传到服务器上，通过unzip nexus-2.12.0-01-bundle.zip本文件夹解压

解压后结果：

![20200302170432874.png][]

启动nexus：进入/root/home/websoft/nexus/nexus-2.12.0-01/bin目录，启动 ./nexus start

如果出现以下问题，可以执行set RUN\_AS\_USER=root，也可以把export RUN\_AS\_USER=root加入到/etc/profile文件中

启动成功后，nexus默认端口8081，[http://47.101.53.139:8081/nexus][http_47.101.53.139_8081_nexus]

右上角可以登录，默认账号admin密码admin123

然后将代理的download remote indexes设置为true，使得可以下载

[http://47.101.53.139:8081/nexus/content/groups/public/][http_47.101.53.139_8081_nexus_content_groups_public] 是我们的仓库地址。

### 4、maven连接nexus配置 ###

在setting.xml中新增server和mirror配置：

<?xml version="1.0" encoding="UTF-8"?>
    
    
    <settings xmlns="http://maven.apache.org/SETTINGS/1.0.0" 
              xmlns:xsi="http://www.w3.org/2001/XMLSchema-instance" 
              xsi:schemaLocation="http://maven.apache.org/SETTINGS/1.0.0 http://maven.apache.org/xsd/settings-1.0.0.xsd">
     
      <pluginGroups>
        
      </pluginGroups>
    
      
      <proxies>
        
      </proxies>
    
      
      <servers>
        <server>
            <id>releases</id>
            <username>admin</username>
            <password>admin123</password>
        </server>
        
        <server>
            <id>snapshots</id>
            <username>admin</username>
            <password>admin123</password>
        </server>
        
        <server>
            <id>thirdparty</id>
            <username>admin</username>
            <password>admin123</password>
        </server>
      </servers>
    
      <mirrors>
            
        <mirror>
          <id>nexus</id>
          <mirrorOf>Central</mirrorOf>
          <name>nexus maven</name>
          <url>http://47.101.53.139:8081/nexus/content/groups/public/</url>
        </mirror>
      </mirrors>
      
     
      <profiles>
        <profile>
          <id>env-dev</id>
    
          <activation>
            <property>
              <name>target-env</name>
              <value>dev</value>
            </property>
          </activation>
    
          <properties>
            <tomcatPath>/path/to/tomcat/instance</tomcatPath>
          </properties>
        </profile>
      </profiles>
    </settings>

如果添加其他的jar包时，会先在nexus私服下载好，以后才会下载到本地。以后，如果发现私服已经存在某一jar包，则会直接从私服下载，如果没有再去网络上下载。

### 5、尝试上传jar包(通过IDEA) ###

上传命令：

mvn deploy:deploy-file -DgroupId=groupId -DartifactId=artifactId -Dversion=version -Dfile=本地jar包路径 -DrepositoryId=releases/snapshots -Durl=仓库地址

举例：上传jmxri-1.2.1.jar，本地存放在D盘

mvn deploy:deploy-file -DgroupId=com.sun.jmx –DartifactId=jmxri -Dversion=1.2.1 -Dfile=d:/jmxri-1.2.1.jar -DrepositoryId=releases -Durl=***http://ip/nexus/content/repositories/releases***

**实际工作中我们可能采用工具上传，以IDEA为例：**

新建一个maven工程，打包方式为pom

<?xml version="1.0" encoding="UTF-8"?>
    <project xmlns="http://maven.apache.org/POM/4.0.0"
    		 xmlns:xsi="http://www.w3.org/2001/XMLSchema-instance"
    		 xsi:schemaLocation="http://maven.apache.org/POM/4.0.0 http://maven.apache.org/xsd/maven-4.0.0.xsd">
    	<modelVersion>4.0.0</modelVersion>
    	
    	<groupId>cn.com.chenwb</groupId>
    	<artifactId>base-pom</artifactId>
    	<version>1.0-SNAPSHOT</version>
    	<packaging>pom</packaging>
    	
    	<properties>
    		<deploy.releaseRepository.url>http://47.101.53.139:8081/nexus/content/repositories/releases/</deploy.releaseRepository.url>
    		<deploy.snapshotRepository.url>http://47.101.53.139:8081/nexus/content/repositories/snapshots/</deploy.snapshotRepository.url>
    	</properties>
    
    	<distributionManagement>
    		<repository>
    			<id>releases</id>
    			<name>releases</name>
    			<url>${deploy.releaseRepository.url}</url>
    		</repository>
    		<snapshotRepository>
    			<id>snapshots</id>
    			<name>snapshots</name>
    			<url>${deploy.snapshotRepository.url}</url>
    		</snapshotRepository>
    	</distributionManagement>
    
    </project>

注意distributionManagement节点，repository中id与setting.xml中的server中id一致，也就是与RepositoryID保持一致

执行depoly，出现400错误：

![watermark_type_ZmFuZ3poZW5naGVpdGk_shadow_10_text_aHR0cHM6Ly9ibG9nLmNzZG4ubmV0L3dlaXhpbl8zNzk2ODYxMw_size_16_color_FFFFFF_t_70 2][]

这里可能的原因是Releases仓库模式是不允许redeploy的，改成allow redeploy。参考：[https://www.iteye.com/blog/zmoxga-1522606][https_www.iteye.com_blog_zmoxga-1522606]

![watermark_type_ZmFuZ3poZW5naGVpdGk_shadow_10_text_aHR0cHM6Ly9ibG9nLmNzZG4ubmV0L3dlaXhpbl8zNzk2ODYxMw_size_16_color_FFFFFF_t_70 3][]

最后deploy成功：

![watermark_type_ZmFuZ3poZW5naGVpdGk_shadow_10_text_aHR0cHM6Ly9ibG9nLmNzZG4ubmV0L3dlaXhpbl8zNzk2ODYxMw_size_16_color_FFFFFF_t_70 4][]

可以在仓库中查看上传的包：
